I just recieved a message from someone who says that I won an Item that He was selling on Ebay and he wants me to Pay for it or he's going to report me to EBay ,He claims to have sent me several e-mails and I have failed to respond to them , so I checked my Ebay account just to see if there was anything that maybe I over looked, I have several things that I'm watching but in the past 60 days it says that I've not won a thing , so am I to assume that this is some kind of a scam , It looks real legit, I think I should notify Ebay , but who do I contact, any suggestions
